Which consequence results when monochromatic light encounters flaws in optical fiber?

💡 Explanation

Modal dispersion increases because constructive interference amplifies certain modes along fiber imperfections; these flaws cause a variation in group delay, therefore the pulse broadens, rather than improved light transmission as suggested in options B, C, and D.
